The Dispersal Ecology of Rhodesian Sleeping Sickness Following Its Introduction to a New Area
No full textTsetse-transmitted human and animal trypanosomiasis are constraints to both human and animal health in sub-Saharan Africa, and although these diseases have been known for over a century, there is little recent evidence demonstrating how the parasites circulate in natural hosts and ecosystems. The spread of Rhodesian sleeping sickness (caused by Trypanosoma brucei rhodesiense) within Uganda over the past 15 years has been linked to the movement of infected, untreated livestock (the predominant reservoir) from endemic areas. However, despite an understanding of the environmental dependencies of sleeping sickness, little research has focused on the environmental factors controlling transmission establishment or the spatially heterogeneous dispersal of disease following a new introduction. In the current study, an annually stratified case-control study of Rhodesian sleeping sickness cases from Serere District, Uganda was used to allow the temporal assessment of correlations between the spatial distribution of sleeping sickness and landscape factors. Significant relationships were detected between Rhodesian sleeping sickness and selected factors, including elevation and the proportion of land which was “seasonally flooding grassland” or “woodlands and dense savannah.” Temporal trends in these relationships were detected, illustrating the dispersal of Rhodesian sleeping sickness into more ‘suitable’ areas over time, with diminishing dependence on the point of introduction in concurrence with an increasing dependence on environmental and landscape factors. These results provide a novel insight into the ecology of Rhodesian sleeping sickness dispersal and may contribute towards the implementation of evidence-based control measures to prevent its further spread

Vascular endothelial growth factor restores delayed tumor progression in tumors depleted of macrophages
No full textGenetic depletion of macrophages in Polyoma Middle T oncoprotein (PyMT)-induced mammary tumors in mice delayed the angiogenic switch and the progression to malignancy. To determine whether vascular endothelial growth factor A (VEGF-A) produced by tumor-associated macrophages regulated the onset of the angiogenic switch, a genetic approach was used to restore expression of VEGF-A into tumors at the benign stages. This stimulated formation of a high-density vessel network and in macrophage-depleted mice, was followed by accelerated tumor progression. The expression of VEGF-A led to a massive infiltration into the tumor of leukocytes that were mostly macrophages. This study suggests that macrophage-produced VEGF regulates malignant progression through stimulating tumor angiogenesis, leukocytic infiltration and tumor cell invasion
Fidelidad del cliente del Hotel JW Marriott el Convento Cusco -2020
No full textEl presente trabajo de investigación se titula “La fidelidad del cliente del hotel JW Marriott El
Convento Cusco-2020”. Teniendo en cuenta que la fidelidad del cliente es un tema que en la
hotelería es uno de los principales intereses y lo vienen desarrollando la mayoría de las cadenas
hoteleras más renombradas, como es Marriott Hotels y específicamente el hotel JW Marriott El
Convento Cusco. En el cual encontramos un problema del cual tratamos en la presente
investigación, la cual se basa en que: si el cliente no pasa satisfactoriamente las fases de
fidelización, no llega a fidelizarse completamente, ello se debe a que existen ciertos aspectos que
impiden una fidelización, es decir que pueden resquebrajar la fidelidad del cliente, por ejemplo los
inconvenientes que puede tener el cliente, ya sea previo al servicio (desde la reserva del servicio
por medio de Online Travel Agency o por otro medio), la entrega o disfrute del servicio (la estadía)
y el post servicio (después del check out del hotel). Por ello, la presente investigación tiene como
objetivo principal describir la fidelidad del cliente del hotel JW Marriott El Convento Cusco-2020.
Como también, los objetivos específicos que describen la fidelidad del cliente en cada una de las
fases de fidelización. La metodología manejada para la elaboración de la presente tesis fue de tipo
cuantitativo, el nivel es descriptivo no experimental.
Se obtuvo datos del autor (Oliver R. , 1999) sobre las fases de la fidelidad del cliente, que son
fidelidad cognitiva, fidelidad afectiva, fidelidad conativa y fidelidad de acción; las cuales se
utilizaron como dimensiones de la variable, describiendo cada una de ellas. Para describir la
fidelidad del cliente del hotel JW Marriott El Convento Cusco-2020 se realizó encuestas vía web
dada la coyuntura actual, con una muestra no probabilística de 102 personas que fueron los clientes
que voluntariamente respondieron el cuestionario.
Según los resultados obtenidos de las encuestas realizadas, se determinó que la fidelidad del cliente
del hotel JW Marriott El Convento Cusco-2020 es muy buena, al igual que sus cuatro fases de
fidelidad del cliente. Debido a que el hotel cumple con todas las expectativas que tiene el cliente y
al final genera una recompra por parte del cliente hacia el hotel JW Marriott El Convento Cusco,
dado por el cumplimiento de las cuatro fases de fidelización del cliente por lo siguiente: El cliente
es inicialmente fiel en un sentido cognitivo basado en la información y creencia que tiene el cliente,
después de las experiencias satisfactorias se genera un sentimiento de compromiso hacia el hotel
siendo fiel afectivamente, para así por medio de intenciones de comportamientos positivos por parte de asociados del hotel siendo fiel conativa, y finalmente el hotel al cumplir con todas las
expectativas del cliente y superar todos los obstáculos posibles se produce un control de la acción
que viene a ser la fidelidad de acción donde se produce la recompra del servicio del hotel JW
Marriott El Convento Cusco y retener al cliente.
Se pudo concluir que, el hotel JW Marriott El Convento Cusco es muy bueno fidelizando a sus
clientes y puede ser mejor incluso, si se siguen las propuestas planteadas. En la investigación, se
ha logrado describir cómo retener a los clientes y generar un compromiso profundo de recompra
del servicio JW Marriott El Convento Cusco por medio de las fases de fidelización.This research is titled “The costumer loyalty of the JW Marriott El Convento Cusco hotel-2020”.
We know that the loyalty in costumers is one of the most important issues for the hospitality
industry and it is been developed by most of the renowned hotel chains in the World, such as
Marriott Hotels and specifically the JW Marriott El Convento Cusco hotel. We found a problem
wich is based on the fact that: if the costumer doesn´t satisfactorily obtain the four loyalty phases,
the client will not become completely loyal to the hotel. This because there are some aspects that
don´t allow the loyalty, for example the pre service (from the reservation of the service through the
Online Travel agency or other method of reservation), the service (the stay) and the post service
(after the check out of the hotel). The main objective of this research is to describe the customer
loyalty of the JW Marriott El Convento Cusco hotel-2020. As well as, the especific objectives, that
describes the customer loyalty in each of the loyalty phases. The methodology used to prepare this
research was quantitative, and the level is descriptive, not experimental.
The data was obtained from the author (Oliver R. , 1999) that explained about the phases of
customer loyalty, which are Cognitive Loyalty, Afective loyalty, Conative loyalty and Action
loyalty; which were used as dimensions, describing each one of them. In order to describe the
costumer loyalty of the JW Marriott El Convento Cusco hotel-2020, we make the surveys via web
because of the current situation, with a non probability sample of 102 people who were the
costumers who voluntarily answered the questionnaire.
The costumer loyalty of the JW Marriott El Convento Cusco hotel -2020 was determined to be very
good, and also the phases of the customer loyalty as well. All that because the hotel meets all the
expectations that the customer has and in the end generates a repurchase by the customer from the
JW Marriott El Convento Cusco hotel, all that with the four phases of the loyalty of the client, and
we can detail that: The cliente initially gets the cognitive loyalty based in the information and
believes that the client has; after the satisfactory experiences, a feeling of commitment to the hotel
is generated, that is the afective loyalty; and for this reason through the intentions of positive
behaviors of the associates of the hotel, that is the conative loyalty; and finally when the hotel
meets all the expectations of the clients and overcoming all the possible obstacles, there is a control
of the action that comes to be the action loyalty, and the repurchase of the service of the JW Marriott
El Convento Cusco hotel occurs and retain more clients. In conclusion, the hotel JW Marriott El Convento Cusco is very good building customers loyalty
and can be better if the proposals proposed are followed. In the research, it has been possible to
describe how to retain customers and generate a deep commitment to repurchase the service of the
JW Marriott El Convento Cusco hotel through the loyalty phases
Information for decision making from imperfect national data: tracking major changes in health care use in Kenya using geostatistics
No full textBackground: most Ministries of Health across Africa invest substantial resources in some form of health management information system (HMIS) to coordinate the routine acquisition and compilation of monthly treatment and attendance records from health facilities nationwide. Despite the expense of these systems, poor data coverage means they are rarely, if ever, used to generate reliable evidence for decision makers. One critical weakness across Africa is the current lack of capacity to effectively monitor patterns of service use through time so that the impacts ofchanges in policy or service delivery can be evaluated. Here, we present a new approach that, for the first time, allows national changes in health service use during a time of major health policy change to be tracked reliably using imperfect data from a national HMIS.Methods: monthly attendance records were obtained from the Kenyan HMIS for 1 271 government-run and 402 faith-based outpatient facilities nationwide between 1996 and 2004. Aspace-time geostatistical model was used to compensate for the large proportion of missing records caused by non-reporting health facilities, allowing robust estimation of monthly and annualuse of services by outpatients during this period.Results: we were able to reconstruct robust time series of mean levels of outpatient utilisation of health facilities at the national level and for all six major provinces in Kenya. These plots revealed reliably for the first time a period of steady nationwide decline in the use of health facilities in Kenyabetween 1996 and 2002, followed by a dramatic increase from 2003. This pattern was consistent across different causes of attendance and was observed independently in each province.Conclusion: the methodological approach presented can compensate for missing records in health information systems to provide robust estimates of national patterns of outpatient service use. This represents the first such use of HMIS data and contributes to the resurrection of these hugely expensive but underused systems as national monitoring tools. Applying this approach to Kenya has yielded output with immediate potential to enhance the capacity of decision makers in monitoring nationwide patterns of service use and assessing the impact of changes in health policy and service deliver
The impact of neutralizer-free ignition of a radio frequency ion thruster on the lifetime of the ion optics system
No full textIn the initial stage of a radio frequency ion thruster (RIT) ignition, an influx of electrons is required from an external source into the discharge chamber and ionization of the neutral gas propellant. A neutralizer-free method for Townsend breakdown discharge ignition based on Paschen's law was developed in this study. The feasibility of the ignition method was confirmed by performing thousands of ignition experiments. Metallic Molybdenum (Mo), pyrolytic graphite (PG) and Zr41.2Ti13.8Cu12.5Ni10Be22.2 alloy acceleration grids were prepared, and ignition-induced damage on the grids was investigated. A field-emission scanning electron microscope was used to inspect surface damage on the grids after multiple ignitions and to analyze the influence of the ignition method on the lifetime of the ion optical system. Grid materials for space missions that require multiple RIT ignitions (10(3)) should be high-strength blocks that are resistant to sputtering corrosion and high temperature.</p
Critical ethnography
No full textCritical ethnography is concerned with relations of power and related issues of dis/advantage in wider social, educational, and political contexts. Critical ethnography can thus best be described as conventional ethnography with a political purpose. While critical ethnography aligns with the wider field of ethnography, it offers and requires a different orientation to the settings under investigation. One of the key aspects of critical ethnographic research is the focus therein on applying social theory to the research framing and analyses. This approach requires writers and researchers to attend not only to issues of ethics, reflexivity, and positionality but also to issues of social class, place, ethnicity, culture, gender, sexuality, the body, among others. Such an approach requires an intertwining of theory and method in sophisticated, nuanced, and coherent ways. Crucially, critical ethnographers are interested in and responsive to theoretical and sociological questions and new knowledge. So, critical ethnographers must also respond to and engage with salient theoretical developments in sociology, anthropology, education, and related fields. Throughout this entry, the key tenets of critical ethnography are highlighted. To do so, the entry draws on a wide range of international examples of critical ethnography, with a particular focus on education, research with youth, sporting contexts, and studies in language and health contexts. This accomplishes two key aims: It provides an overarching thematic and historical overview of critical ethnographic work and addresses contemporary issues of power and inequality and their often complex intersectionality
